Abstract
A preparation method of a flame-retardant waterproof high-gram-weight paper board is characterized by including the following steps that 1, two layers of 200 g/<2> craft paper are used and two layers of 175 g/m<2> liner paper are used, wherein the two layers of liner paper adhere to each other through starch adhesive on the same single facer to generate composite paper of 400 g/m<2>, and then the composite paper and the two layers of 200 g/m<2> craft paper adhere to each other through starch adhesive on a double facer to be a 900 g/m<2> paper board through drying; 2, the front and back faces of the 900 g/m<2> paper board are painted with flame-retardant coating respectively and dried through a hot plate of a corrugated board line to form the high-gram-weight waterproof flame-retardant paper board. The whole high-gram-weight flame-retardant waterproof paper board is completed on the corrugated board line all the way.
Description
Technical field
The preparation method that the present invention relates to a kind of high grammes per square metre cardboard with fire resistance and water resistance.
Background technology
Owing to corrugated board factory there is no the paper mill of oneself, it is impossible to according to the paper using specification requirement of oneself, meet collocation paper using demand, only by consulting with paper mill to coordinate production needs. On market, the quantitative Concha Arcae paper using of the height sold is typically in 200��300 grams/m2Between, the high grammes per square metre Concha Arcae paper using of import is usually no more than 440 grams/m2. For the paper using specification of the high grammes per square metre of some specific use, corrugated board factory can only seek help and have no other way with paper mill.
One of flame resistant method for flame-retardant waterproof corrugated case is to try to reduce the offer of oxygen when burning. If still adopting corrugated corrugated paper complex technique in the middle of this novel carton, the supply of oxygen when burning will be increased, thus improve the difficulty reaching flame retardant effect; If the cardboard adopting high grammes per square metre replaces, owing to not having oxygen contained by Concha Arcae ripple space and the cross-ventilated probability formed with Concha Arcae ripple for passage, this will reduce the supply of oxygen during burning. And the paper of high grammes per square metre can improve the paper adsorbance to fire retardant, reaches better flame retardant effect.
It addition, the research of the fire-retardant cardboard of the honeycomb type of simple function also has been reported that, its flame retardant effect is also goodish, but maximum haveing the drawback that can not realize serialization commercial production in corrugated board factory, and corrugated paper board production line can not meet its production requirement.
Adopt high grammes per square metre cardboard as the base material of carton, it is possible to overcome with corrugated Concha Arcae for the base material negative effect to flame retardant effect, reduce the supply of oxygen.
The burning of plant fiber material paper material is mainly cellulose generation thermal degradation reaction and produces low molecular weight volatile gas, the diffusion of escaping gas and conduction of heat, make propagation of flame to contiguous material surface and be heated to thermal degradation temperature, make burning constantly go on. Cause three conditions of generation needs of combustion process: combustible, temperature and oxygen. The method being mainly obtained by physics and chemistry of flame retardant effect makes the condition of above-mentioned burning lack one or several, reaches fire-retardant purpose.
The development of fire retardant is always up the study hotspot of fire retardant papers, and relevant research also appears in the newspapers repeatly. But the compound prescription of fire retardant does not describe in detail, simply report its fire-retardant effect, and this based flame retardant is mainly added in paper pulp, namely add in paper-making process. But corrugated case factory is can not arbitrarily according to the Production requirement of self, and carrying out the production of requirement paper mill provides the product meeting its requirement.
Waterproofing agent produces waterproof effect and mainly relies on functional group in waterproofing agent and fiber generation cross-linking reaction or utilize the low-surface-energy of carbon fluorohydrocarbon in waterproofing agent to reach waterproof effect.The waterproof effect generally reached with cross-linking reaction is not waterproof truly, simply improves the wet strength of paper, and paper still can absorb a certain amount of moisture content, and these waterproofing agents are also all added to starch interior use, does not meet research and requires. At present, the research of waterproofing agent used by impermeable paper products is concentrated mainly on carbon fluorine class waterproofing agent this on the one hand, its waterproof effect is commonly considered as the maximum electronegativity due to fluorine, radius is slightly big than hydrogen, carbochain can be covered well, and fluorine-containing alkyl functional group aligns the outermost layer at polymer, Air Interface, can form thin film at fibrous outer surfaces, it is that fiber surface tension force significantly reduces, and then reaches water-proof function. The good water-proof effect of this kind of waterproofing agent, but cost is of a relatively high, adds time also in slurry simultaneously, thus use and be subject to certain restrictions.
Fire retardant mainly have into paper with the interpolation of waterproofing agent before slurry in additive process with become the infusion process after paper, rubbing method and size press method etc. Said method is respectively arranged with pluses and minuses. In general, fire retardant is hydrophilic, and waterproofing agent is inflammable, the actual effect of both aggregate balancings, finds equilibrium point between. The chance contacted with water due to daily carton used contacts much larger than with fire, thus during equilibrium point with waterproof effect fire-retardant in searching, first has to consider to meet enough waterproof effects, then promote its flame retardant effect more as much as possible. Therefore the selection of fire retardant and waterproofing agent addition manner is particularly important.
